Definitions

  • EP-A-1 029 018 teaches the use of microcapsules having a capsule wall comprising a highly crosslinked methacrylic ester polymer and a latent heat accumulator core in binding building materials such as concrete or gypsum. Since the capsule walls only have a thickness in the range from 5 to 500 nm, however they are very pressure-sensitive, an effect which is utilized in their use in copying papers. However, this limits their usability.
  • Preferred preparations comprise 55-94% by weigh of latent heat accumulator material, 1-40% by weight, preferably 1-30% by weight, of polymeric binder, calculated as solid, microcapsule wall material and 0-10% by weight of other additives, based on their total weight.
  • the capsule core-forming substances may be advantageous to add to the capsule core-forming substances compounds which are soluble in them, in order to prevent the freezing point depression which occurs in the case of some of the nonpolar substances.
  • compounds having a melting point which is from 20 to 120 K higher than the actual core substance are advantageously used.
  • Suitable compounds are the fatty acids, fatty alcohols, fatty amides and aliphatic hydrocarbon compounds mentioned above as lipophilic substances. They are added in amounts of from 0.1 to 10% by weight, based on the capsule core.
  • Formaldehyde resins preferred as capsule wall material are urea/formaldehyde resins urea/resorcinol/formaldehyde resins, urea/melamine resins and melamine/formaldehyde resins.
  • the C 1 -C 4 -alkyl ethers, in particular methyl ethers of these formaldehyde resins and the mixtures with these formaldehyde resins are likewise preferred.
  • Melamine/formaldehyde resins and/or methyl ethers thereof are particularly preferred.
  • the inorganic protective colloids are to be used as a rule in amounts of from 0.5 to 15% by weight, based on the aqueous phase.
  • Polymeric binders are generally known. These are fluid systems which comprise, as the disperse phase in an aqueous dispersing medium, polymer coils which consist of a plurality of entangled polymer chains, the so-called polymer matrix or polymer particles, in a disperse distribution.
  • the weight average diameter of the polymer particles is frequently in the range from 10 to 1000 nm, often from 50 to 500 nm or from 100 to 400 nm.
  • the polymeric binder comprises the assistants described below.
  • the binder polymers according to the invention preferably have thermoplastic properties. Thermoplastic is to be understood as meaning that the binder polymers soften without decomposition above the glass transition temperature.
  • Preferred film-forming polymers are selected from the polymer classes I to IV mentioned below:
  • polymer powders prepared from the polymer dispersions and aqueous dispersions which are obtainable by redispersing the polymer powders in water are likewise preferred.
  • aqueous polymer dispersions and the powders prepared therefrom are moreover commercially available, for example under the brands ACRONAL®, STYRONAL®, BUTOFAN®, STYROFAN® and KOLLICOAT® from BASF Aktiengesellschaft, Ludwigshafen, Germany, VINNOFIL® and VINNAPAS® from Wacker Chemie-GmbH, Burghausen, and RHODIMAX® from Rhodia S.A.
  • the coarse-particled microcapsule preparations are outstandingly suitable for use in building materials and as storage material in heat exchangers. They exhibit good hardness and are abrasion-resistant. Their coarse-particled structure permits freely selectable accumulator geometry, for example beds for floor coverings, chemical reactors or columns, and in applications involving through-flow, such as heat exchangers, in solar units, heating systems, in particular warm air heating systems, and central and localized ventilation.
